IUCr 1996 Report - Int. Tables Volume H. Maximal Subgroups of Space and Plane Groups

In August 1995, the Executive Committee approved this volume, which will complete data on maximal subgroups of space and plane groups. H. Wondratschek has been appointed Editor; Co-authors are M. I. Aroyo and Y. Billiet. The contents of this volume and of the form of the data can be found in Acta Cryst (1996), A52, 94.

Contents

Part 1. Introduction: List of symbols, User's guide to the tables, Coordinate transformations.

Part 2. Tables: Tables of all maximal subgroups and minimal supergroups for each plane and space group. Diagrams: Diagrams for translationengleiche and klassengleiche subgroups for each plane and space group.

Part 3. Mathematical and Practical Aspects: Group-theoretical background. Applications.

Present state

The data have been calculated completely and transferred to forms programmed in LaTeX 2e. The forms are now being checked by the Technical Editor as to whether the tables can be printed directly from them. All diagrams have been hand drawn and sent to the Technical Editor for tests. There is a draft by G. Nebe of the mathematical section. For the section on applications of subgroups, an author still has to be found.

The year 1996 was devoted mainly to the typing of the subgroup tables. For 1997, checking of the data, adjusting of the forms and writing the missing text sections is anticipated.
